Chassis Center Of Gravity; Permissible Height Of Center Of Gravity - Unimog U500 Mounting Manuallines

Body and Implement Mounting Guidelines U500 North America
Note: The actual tilting angle between the body and the
vertical is significantly greater as a result of unilat-
eral spring deflection. The static tilting test must only
be carried out by experienced personnel using suit-
able restraining facilities of suitable dimensions. The
static tilting angle must be determined precisely on a
tilting stage.

Chassis center of gravity

The following center of gravity heights of the chassis are esti-
mated values with the empty vehicle in its permissible GVW
spring-deflected state without platform or platform subframe.

Table 4.5: Chassis center of gravity
*Note: The center of gravity height above the road surface is
calculated using the 395/85 R20 XZL (Code R34) tires.
For other tires please use data of Table 4.3, page 74 and
calculate the c.o.g. height above the road surface with
Equation 4.5, page 74 by yourself.

Permissible height of center of gravity

The design of the implement or body must ensure that the overall
height of the center of gravity (vehicle with all implements and/or
bodies and payload) is as low as possible.
C.o.g. height above the road surface
up to 51 in
between 51 in
and 59 in
between 59 in
and 67 in
above 67 in

Notes:
1)
Restrictions for c.o.g. height between 51 in and 59 in:
*
Practical road trials and approval by the Freightliner Unimog
department required, definition of restrictions necessary (e.g.
[mm]
instruction of drivers, limited off-road-capability, reduced maxi-
mum speed to 55 mph or less)

Restrictions for c.o.g. height between 59 in and 67 in:
Practical road trials and approval by the Freightliner Unimog
department required, definition of restrictions necessary (e.g.
instruction of drivers, limited off-road-capability, reduced maxi-
mum speed to 35 mph or less, no off-road use!)
3)
Exceptions possible, e.g. operations in restricted areas and at
very low driving speed < 10 mph
